GAS BURNER.

certain new. and useful Improvements 'in Gas-Burners, of which the following is a specification.

This invention relatesto new and useful improvements in gas burners, Particularly to that type of gas burner adapted tobe used in connection -with boilers and furnaces, and the primary object thereof is to provide a burner of the type stated, in a manner as hereinafter set forth, whereby the flames from the burner may be directed and distributed against the surface to be heated regardless of'the contour of the in terior of the combustion'chamber in'which the burner is positioned, thereby assuring the economical and eflicient use of gas in connection therewith.

Further objects of this invention are to provide a device of the character described which is simple in'its construction and arrangement, strong, durable and efiicientin its use, readily assembled and demounted, adjustable, and comparatively inexpensive to manufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that the device shown is merely illustrative and that various changes in the form, proportion and minor details of construction may be resorted to, without departing from the principle or sacrificing any of the advantages of the invention, which come within the scope of the claims hereunto appended.

In the drawing forming a portion of this specification and wherein like numerals of. reference designate corresponding parts throughout the several views:

Figure 1 is a transverse sectional elevation of a gas burner in accordance with this invention.

Fig. 2 is a longitudinal sectional view thereof. I

Fig. 3 is an elevation of the mixer element.

Application filed January. 3, 1920. Serial No..349,211.

Fig. 4 is a top plan view of a-modifica' tion. y

Referring to Figs. lto 3, of the drawing, the. burner comprises a body portion .1

formed of an elongated hollow cylindrical member, closed at oneend by a cap: 2, and adapted to have its other end connected with a gas supply pipe, not shown; the connection being in any manner desired.

I The body portion 1 isprovided with a plurality of radially disposed openings 3, having threadedwalls and these latterare employed for connecting a mixer element or a-closure plug 4 to thebody portion. The number andarrangement of the openings 3, in the .body portion 1, may be as desired to best meet conditions found in'practice.

The mixer element comprises anaper tured mixer pin 5, having a shank. 6 formed with a threaded periphery and the shoulder portion 7 a The threaded shank 6 connects with the threaded wall ofan opening 3, whereby the mixer pin 5 is secured to the body portion 1. The mixer pin 5 communicates with the interior of the body portion 1, as clearly shown in Figs. 1 and 2, of the drawing. tion 7 and surrounding the mixer pin 5, as well as being secured to the latter by-a set screw 8, is a collar 9, the later having formed integral with its'periphery a pair of outwardly projecting opposed arms 10 which terminate in the periphery of a band 11, the latter being spaced from the collar 9 to provide an inlet for air to the inner end of the burner tube 12, which extends through the band 11 and is adjustably connected 'with the latter byga set screw 13.

The burner tubesi 12 are elongated'and each of a length whereby the flame at the outer end of thetube willbe positioned to properly and efficiently contact with the surface which is to be heated.

The tubes 12 are radially disposed and may be of different lengths to best meet conditions encountered. When tubes 12 are not connected to certain of the openings 3, these latter openings are closed by the plugs 4 to prevent the escape of gas therethrough.

The outer ends of the tubes 12 have peripheral threads for connectingtherewith a burner tip 14, the latter being T-shaped and has the horizontal leg thereof closed by plugs 15, and the said horizontal leg of the tip 14 is furthermoreprovided with spaced Specification of Letters Patent. Patented Sept; 20, 1921; v

ounted upon the shoulder porg 7 high pressure gas is used the burner tubes 12 are employed without the tips 14:. c

The burner tubes 12 are so set up and of v such lengths that they will extend in proximity to the surface to be heated so that the flame will come in direct contact'with such surface and quickly and intensely heat same. The burner is employed primarily in con nection with portable boilers and furnaces, but'it. is obvious that the burner can be employed for any purposes wherein it is found applicable.

In Fig. 1 of the'drawing the body portlon of the burner is shown as formed of a single hollow cylindrical member, while in the modified form, shown in Fig. 4, the body portion is illustrated as consisting of a pair of hollow cylindrical members 17 and 18, each having one end closed by the caps 19, and its other end attached to an elbow coupling-20. Secured to the elbow couplings 20 is a connecting or conducting pipe 21, which has attached thereto a gas supply pipe 22. The form of burner tube, burner tip, mixer element, and closure plug, is the same as that shown in Fig. Land-such elements of the structure are indicated at 23, 24:, 25 and 26, respectively.

It is obvious that the body portion can consist of any number of hollow cylindrical members, that is to say, one or more.

What I claim is: 1

1. A gas burner comprising a hollow cylindrical element adapted to be connected with a gas supply and having a plurality of openings, a vertically disposed and a plurality of upwardly inclined mixer elements secured in said openings, and a burner tube mounted in each, of the-mixer elements and extending in thesame direction throughout asits respective mixer element.

2. A gas burner comprising a hollow cylindrical element adapted to be connected with a gas supply and having a plurality )f openings, a vertically disposed and a pluthereto.

rality of upwardly inclined mixer elements secured in said openings, a burner tube mounted in each of the mixer elements and extending in the same direction throughout as its respective mixer elements, each of said mixer elements provided at its outer end with means whereby the tube carried there-- i by can be lengthwise adjusted relatively 3. A gas burner comprising'an elongated o hollow cylindrical memberadapted to be connected with a gas supply and'having a series of openings, a vertically disposed and a plurality of upwardly inclined mixerelements secured in said openings, said inclined mixer elements disposed on opposite sides of. said member, and'a burner tube mounted in each of the mixer elements and extending in the same direction throughout as its respective mixer element.

4. A, gas burner comprising a hollow element adapted to communicate with a gas supply and provided. with openings disposed vertically and at an upward inclination, vertically disposed and upwardly inclined mixer elements securedin said openings, vertically disposed and upwardly inclined 7 burner tubes mounted'in said elements, and saidelements at their outer ends provided with means whereby the burner tubes can be lengthwise adjusted within and relative to said elements.

5. A gas burner comprising a hollow element adapted to communicate with a gas supply and provided with openings disposed vertically and at an upward inclination, vertically disposed and upwardly inclined mixer elements secured in said openings,vertically disposed and upwardly inclined burner tubes mounted in said elements, said elements provided with means whereby the burner tubes can be lengthwise adjusted within. and relative 'to said elements, and T-shaped slotted tips mounted on the outer ends of said tubes. c

In testimony whereof I aflix my signature.
